If you are a dedicated energy drink consumer, you may want to heed the advice of this man.

Dan Royals, a teacher in the UK, would regularly down around six energy drinks a day.

Now, his doctor and Dan himself are spreading the message that the sugar-riddled and chemical-like drinks are terrible for you, as his tongue was literally ‘eaten away’ by them.

In a Facebook post accompanied with a pic of his tongue, Dan wrote, “Who drinks energy drinks? Addicted to them? You may want to think again.” He continued, “Have a look at the second pic… that’s what that s*** does to your tongue, imagine what it’s like on your internals?”
